Functional connectivity in the motor cortex of resting human brain using echo‐planar mri
Abstract An MRI time course of 512 echo‐planar images (EPI) in resting human brain obtained every 250 ms reveals fluctuations in signal intensity in each pixel that have a physi...
Stellar population synthesis at the resolution of 2003
We present a new model for computing the spectral evolution of stellar populations at ages between 100,000 yr and 20 Gyr at a resolution of 3 A across the whole wavelength range...
Orbital angular momentum of light and the transformation of Laguerre-Gaussian laser modes
Laser light with a Laguerre-Gaussian amplitude distribution is found to have a well-defined orbital angular momentum. An astigmatic optical system may be used to transform a hig...
TCS: a computer program to estimate gene genealogies
Phylogenies are extremely useful tools, not only for establishing genealogical relationships among a group of organisms or their parts (e.g. genes), but also for a variety of re...
Positive psychology: An introduction.
A science of positive subjective experience, positive individual traits, and positive institutions promises to improve quality of life and prevent the pathologies that arise whe...

The Sloan Digital Sky Survey: Technical Summary
The Sloan Digital Sky Survey (SDSS) will provide the data to support detailed investigations of the distribution of luminous and nonluminous matter in the universe: a photometri...
Free Radicals in the Physiological Control of Cell Function
At high concentrations, free radicals and radical-derived, nonradical reactive species are hazardous for living organisms and damage all major cellular constituents. At moderate...
Measuring the Accuracy of Diagnostic Systems
Diagnostic systems of several kinds are used to distinguish between two classes of events, essentially "signals" and "noise." For them, analysis in terms of the "relative operat...
Statistical parametric maps in functional imaging: A general linear approach
Abstract Statistical parametric maps are spatially extended statistical processes that are used to test hypotheses about regionally specific effects in neuroimaging data. The mo...
